Problems solved by technology

[0004] Although both polyester and acrylic can be dyed with disperse dyes, due to the different distribution of dyes on the two fibers, especially when the two fibers are blended, polyester has much higher competition for disperse dyes than acrylic, and it is very difficult to use only disperse dyes. It is difficult to dye polyester-acrylic blended knitted fabrics in uniform color

Embodiment

[0016] (a) Dyeing: Put the polyester-acrylic blended knitted fabric into 98% acetic acid 0.3-0.5mL / L, urea 0.1-0.5g / L, dispersant 0-0.5g / L, dyeing aid 1-2g / L In the dyeing bath, then add disperse dyes and cationic dyes, and then start to heat up after walking evenly in the dyeing vat. The initial dyeing temperature is about 60°C, and the temperature is raised to 90°C at 1°C / min and then kept for 20 minutes. min Slowly heat up to 105°C, continue dyeing for 60min;

[0017] (b) Cleaning: Cool the polyester-acrylic blended knitted fabric to 60°C and put in 0.5-1.0g / L of trisodium phosphate, 0.5-1.0g / L of hydrosulfite, and 0-1g / L of non-ionic detergent Wash in the clean washing liquid, the bath ratio is 1:10-15, the temperature is 50-60°C, and the time is 10-20min;

[0018] (c) Washing: Wash the nitrile blended knitted fabric with clean water.

Description

[0001] technical field [0002] The invention belongs to a fabric dyeing process, in particular to a polyester-acrylic blended knitted fabric dyeing process. [0003] Background technique [0004] Although both polyester and acrylic can be dyed with disperse dyes, due to the different distribution of dyes on the two fibers, especially when the two fibers are blended, polyester has much higher competition for disperse dyes than acrylic, and it is very difficult to use only disperse dyes. It is difficult to dye polyester-acrylic blended knitted fabrics in a uniform color. [0005] Contents of the invention [0006] In order to overcome the above-mentioned defects in the prior art, the object of the present invention is to provide a dyeing process for polyester-acrylic blended knitted fabrics, which can be dyed evenly. [0007] The dyeing process of polyester-acrylic blended knitted fabric provided by the invention has the following steps: [0008] (a) Dyeing: Put the pol...
